From Kamil Rudnicki:
The Desktop Manager will automatically change your computers desktop wallpaper. Desktop Manager is easy-to-use program, which can add attractive calendar, filters, and effects to your wallpaper. It works with most popular image formats. You can change the wallpaper at regular intervals, or only when windows starts, sorted by order or randomized. You can even create categories for your wallpapers.
What's new in this version:
Version 2.0 works on many image formats, includes new appearance and calendar.
The interface is quite easy and intuitive. The calendar placement option is excellent. I was able to place it where I wanted as to not cover faces in my photos. The fonts were easy to read.
I uninstalled it for two reasons: 1) the center option for photos didn't shrink the photo to fit my screen so only a portion showed. The stretch option fit to screen but distorted the photo. I wanted it to shrink to fit but not distort, even if black backround showed on left & right sides of photo. 2) Calendar columns are placed Monday to Sunday, not Sunday to Saturday; cannot change this confusing format.
